That's not directly related. Of course the result for "HELO museum"
is NONE because "nslookup -q=txt museum." doesn't find an SPF policy.
I think... checking... yes, no policy => NONE.
But for a:%{h} you'd ask for q=a (or q=aaaa), not q=txt (or q=spf),
and they really have an IP. How good that idea is is a separate
question, they (ab)use it for a wildcard.
But "museum" isn't the only TLD with an IP. There might be even a
TLD with an SPF policy... <shudder />
SPF policies can't talk about such domains _directly_ because they
don't have the reqired dot before a <toplabel>. But that doesn't
affect indirect references like "a:%{h}", "mx:%{d}", or "ptr:%{o}".
